I can't get the versions of sampleenc and sampledec in the manual to
work back-to-back. I've tried using speex 1.0.4 and 1.1.6. What am I
doing wrong?
[gerv@otter]$ file in.wav
in.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit,
mono 8000 Hz
Strip headers:
[gerv@otter]$ sox in.wav in.raw
Command as given on manual page:
[gerv@otter]$ ./sampleenc in.raw | ./sampledec out.raw
Re-add headers:
[gerv@otter]$ sox -r 8000 -w -s out.raw out.wav
If I then play back out.wav using mplayer, I get a horrible noise - a
continuous loud hum with bursts of static where the speech was.
Converting in.raw to a temporary wav file (using that last command-line)
and playing it back works fine. So the sampleenc/sampledec pair is doing
something funny to my data.
Looking at the audio waveform using audacity, it looks like some sort of
overflow/wrapping problem...
